IMPROVEMENT IN CAR-COUPLING PINS.

Specification forming part o1" Lcttt'rs Patent No. 149,743, dated April 14, 18.74; application filed November 20, 1873.

which will prevent the pin from working out of the pin-hole in the draw-bar of the car, and causing the cars to become detached while in motion. It consists of an attachment to the ordinary railroad-car coupling-pin.

The pin is manufactured for 'its accommoda- -tion thus: A hole, large enough to admit an iron rod one-fourth of an inchk in diameter, is drilled through the pin A from end to end, passing through the center. In the lower end ofthe pi-n A is drilled a hole about threefourths (i) of an inch in diameter, and 011e inch deep. Through the hole in the pin A is passed the small iron rod B, one-fourth (i) of au inch in diameter, which extends belovir the lower end of the pin about one-half of an inch, and the other end extends above the upper end of the pin, when straight, far enough to bend over, forming a loop, O, for the hand.

The lower end ofthe loop forms a shoulder,

which prevents the rod B from slipping down farther than necessary. On the lower end of the rod B is a iat forged head, and formed over this, in themolds, is a rubber attachment of one piece of rubber, consisting of a rubber cylinder, D, about three -fourths of an inch in length, and one and one-fourth (l) of an inch in diameter, the rod runnin g through the center of said attachment D from end to end. On the lower end of this is formed a circular rubber plate or llange one-eighth (el) of an inch or more in thickness and two (2) inches in diameter. This rubber attachment is drawn into the cavity in the lower end ot' the pin A by pulling up on the small rod D, and, While thus adjusted, the lower end ofthe pin A is unobstructed, and can be rca-(lily inserted in the hole in the draw-bar of the car. When in, the lower end cxtendin g through the draw-bar, the rubber attachment is forced out of the cavity by pressing on the small rod,and the plate or flange resumes its extended or natural position. It being at right angles with the pin A, and larger than the pin-hole in the draw-bar, the pin is prevented from Working out by reason of the motion of the cars.

I am aware that I am not the first to invent a device for preventing the accidental displacement of the coupling-pin, for such a device is embraced in patent to S. A. Otis, October 7, 1873, and such I do not claim, broadly; but

W'hat I do claim as my invention, and desire to secure by Letters Patent, is-

The coupling-pin A, rod B, and rubber block D, combined. as and for the purpose set forth.
